A decent generic Circuit for beginner and intermediates

Well I gave this circuit training a shot on Saturday, and I made it,.... up to the point where I was supposed to run on the treadmill. Didn't quite make it to that point as been having some leg and knee issues and didn't want to push it. So, I kind of modified it to my situation and made it two rounds before I switched back to my regular routine. Hardest part for me was the planks - my whole body was shaking.
So, I've got the info stored in my gym bag, and will try it again when I'm feeling the need for a challenge and a change... Will keep trying that running thing once my leg and knee get back to a more normal state
